Highway 100 Enhancement Concept

Plans for the median enhancements along Highway 100 in Washington are close to being finalized.

The consultant working on the plans, Crawford, Murphy & Tilly Inc. (CMT), submitted a final draft plan to city officials and the Missouri Department of Transportation (MoDOT).

Once those two entities sign off on the final design, the city can begin seeking bids, according to City Engineer Dan Boyce.

Plans were shown to council members after Monday’s administration/operations committee meeting.

MoDOT gave the city a mandate to award a construction contract by the end of September 2012.

Last month, Boyce said bids could be sought in late July and a construction contract could be awarded in late August. Construction could begin in the fall or spring, depending on the contractor chosen.

The updated plans include adding a total of 1,766 feet of median landscaping along three different sections of Highway 100 between Highway 47 and a point east of A. Roy Drive and an option to add a fourth landscaped median for 1,075 feet between International Avenue and Brookview Drive.

Boyce said the entire project, including the alternate area, will be included in the bid package.

“We’ll look at the bid numbers and then decide” if the alternative will be included in the final contract, Boyce said.

Boyce told The Missourian Monday he hopes the city can build at least half of the alternate landscaped median.

The plans call for the following areas to have medians with plantings:

• From a point west of the JCPenney store for about 756 feet;

• From a point east of Washington Heights Drive for 250 feet; and

• From a point east of the Wal-Mart SuperCenter entrance at A. Roy Drive to the east for about 760 feet.

The alternate median area would be located between International Avenue and Brookview Drive. The raised median would start about 400 feet from each of those intersections.


Boyce said all of the planted medians will be irrigated. The Washington Urban Forestry Council and Dave Wehmeyer, of Hillermann Nursery & Florist, provided input on the types of plants to be used.

Plans call for four redpointe maple trees that can grow up to 30 feet tall and 15 feet wide just to the east of the Wal-Mart entrance. Boyce said he believes the trees will not hinder views of motorists.

The rest of the landscaped areas will be planted with native wildflowers and grasses that can grow from 1.5 to 3 feet tall. There also are areas where 3- to 5-foot-tall shrubs will be planted.

Types of grasses and plants include Gro-low Sumac, Autumn Magic Black Chokeberry, Prairie Blazing Star, New England Aster, Prairie Dropseed, Little Bluestem, Black-eyed Susans, Purple Coneflowers and Butterfly Milkweed.

Boyce said there also will be five wayfinding signs and a bike path with signs and striping along the shoulders of Highway 100 from Highway 47 to a point east of East Fifth Street/South Point Road.

The city was awarded a $604,823 federal transportation grant for the project. The grant money is dedicated for enhancement projects only and may not be used for other purposes.

The city’s local match is $151,206, which will be funded with money from the half-cent transportation sales tax.

The council unanimously approved a $69,815.59 contract with CMT to design the enhancements.
